Add subtitle synchronization plugin
I know totem strives to keep things simple but I don't think subtitle timing adjustment is feature bloat, specially if added by a plugin.
In my experience, many subtitles you can download are almost ok except for a couple of interactive tweaks you have to do now and then while playing the movie. But being completely unable to do these tweaks may be the difference between being able to see a movie at all (since for some movies there is no perfect subtitle offer) or having to cross fingers and download some more GBs in order to hopefully find a movie that matches the available subtitles.
